[Mate 8 General] jbmc83:
well the sleep issue definitely isnt right, thats way too much for idle. make sure to enable flight mode in the night and switch off all sensors, then check again, it should be in the range of 0-2% for 8 hours.

as for your sot, 6.5h is actually fine considering your usage scenario. basically everything u do drains way more battery than my usage, for example:

- you use 4g, i use 3g

- you never use wifi, i do that a lot

- you stream tons of videos over mobile network, i only do that on wifi, if at all

- you play games, and that on mobile network! i never do that

- you use two active sims, i only use one

put all those factors together and you have your answer, why you end up with 6.5h sot while im in the range of 10h :)

im not saying you should completely change your usage :D just saying that for your type of usage this sot value is actually not that bad!

I understand you are using KangVIP Slim B357 with AL10. Can this be used on L29 and expect similar results?
[Mate 8 General] jbmc83:
with similar usage, sure. kangvip slim comes with merged cust, thus all mate 8 models are supported. also, new B380 kangvip is coming up soon, B357 is already "old" :D i just cant bother to upgrade every few weeks ;) especially when im this happy with the rom, everything works as it should :)

I'm confused... (sorry i'm knew at the mate 8) how did you change from c432 to c900? I thought they were too different models and they werent compatilble? I have the Portuguese version of L29.
[Mate 8 General] dlorean:
Because I flashed the B162 with twrp. With stock recovery (dload) u can only flash the update, which is for your cust (C432).

[Mate 8 General] loudog3114:
SO, I only get about 6-7 hours SOT over 36ish hours usually of power on time. Can you guys getting toward the double-digits describe the settings you have? Are you on wifi the whole time? Wifi on while screen off? 4g disabled/enabled? Etc. Thanks.
[Mate 8 General] jbmc83:
well it always depends what u do, of course. the longer u stretch out the complete time frame in which u drain the battery, the less SOT u will get. so over a period of 36 hours ull naturally get less SOT than inside of 24 hours, even if your usage patterns are the same :)

in my case its most likely two major factors: first is wifi, which im on most of the time. second one is the firmware! B133 / B162 international firmwares give me those 10-12h SOTs, whereas on B156 chinese rom I only got around 7.5 - 9 hours.
[Mate 8 General] loudog3114:
Obviously, but I am more interested in specific settings. Do you have wifi set to be on when the screen is off?
[Mate 8 General] jbmc83:
yes, its set on always on. which firmware are u sporting?
[Mate 8 General] loudog3114:
Just switched my wifi settings to match yours. Also just flashed b160 international, I have an al10.
[Mate 8 General] ShaQ Blogs:
Thanks for the reply!

I guess I'm on the same boat. I don't see myself upgrading ROM every month or so. Just looking for a stable one with best battery life.

Have a couple of quick questions, hope you can help me with them.

1. As per instructions for KangVIP Slim, I need to flash B1xx stock first (I have the L29).

Instruction from the thread -> Not for directl update from B172, B180 etc. You've to flash B3xx/B320 stock ROM first! L29 users return to B1xx stock and flash B320 international with dload method first, please!

As per DC Unlocker, before unlocking my firmware is -> Firmware : NXT-C900B180.

Currently what I have flashed is C185B190. C900 is kinda confusing me here.

What is the B1xx stock version I need to use?

2. I searched around and was unable to find the B357 links, only B368.

With respect to battery and stability, should I go with B368 or stick with B357?
[Mate 8 General] jbmc83:
what was your original firmware? once u flash a firmware with different cust (Cxx code of firmware name) on top of your original firmware, your cust changes to C900 region (global). so im guessing your original cust is not C185, otherwise it would have still shown that ;) im guessing its either C636 or C432, so you should flash the latest of one of those to ur phone to return it to full stock via update.app method.

once ure on stock B1xx, u can flash a matching B3xx firmware (either with correct cust or with a different but compatible one, i.e. C185 in your case)

once ure on stock B3xx firmware u can flash kangvip slim. B368 is the current version, B357 is a bit older. both are great concerning battery life, based on my own experiences and those of other users here, so you should be fine with B368.

Tried the Kang 368. Battery drainer for sure. I had my battery draining almost 10% overnight. SOT was much lower compared to 190 that I had previously.

Pretty much similar usage with same radios on, same apps alive. From GSam my phone is in deep sleep most of that time. Even during day while using, i found it drains battery quicker.

Android System/Android OS was the culprit with upto 200-300mA per hour of battery drain.

Came back to B180 (1% drain overnight). SOT looks much better. Might up to 190.

With Nougat BETA, battery life decreased from 7h to around 5h...
[Mate 8 General] sharkonland:
Have had the phone for a month now, My analysis so far:

Model: 3gb 32gb, L29C636B320 FW. 1 sim on 4g and microsd in the other slot. All settings stock:

Long story short, totally depends on your usage, but can last very very long and overall excellent battery life.

Detailed scenario for me: Played a game the there day(never alone), which did not seemed fully optimised as was lagging slightly and phone was getting warm, and got 2hrs sot with 55% left from full. Another time, played limbo, optimised game, and got about 2hrs sot time with about 70% remaining from full. And last night was using calculator and note application dual window, and got 1hr sot with 90% remaining(10-15% brightness, but other tests on 50%). Also, normal browsing on chrome gets me around 30-40min per 10%.

Moral of story, mainly depends on what you are doing. A person with light usage such as browsing, texts, basic apps with get much better sot that one playing heavy games or 1080p youtube non stop.

Hope this helps other that get confused as to why there sot numbers are different than other. There are other factors as well, such as condition of battery, brightness level, your local area signal quality, firmware, background notifications and activities, etc. So keep that in mind as well.
[Mate 8 General] robert_123:
For me the problem is battery drain in stand by, 4 percent per hour. Android system is reported to drain 70 percent of total battery drain.
[Mate 8 General] tboy2000:
Not sure what is going on. After full charge I used to get straight away around 48hrs standby. Recently it was 24hrs and this morning it said 16hrs. What the heck is going on? My usage is the same since many months. Same stuff running in background. Nothing changed. Dodgy battery?
[Mate 8 General] shadovraven:
Every single update worsens the battery life. It was excellent on B152, solid but weaker on B170 and its complete garbage on B192 (hard reset everytime , which should be obvious). So don't say that b192 has excellent battery life, it doesn't.

B152 - 1% per 10 minutes of chrome browsing,

B170 - 1% per 8 minutes of chrome browsing,

B192 - 1% per 4/5 minutes of chrome browsing.

Clean os, same settings, same accounts added and same version of browser. Amazing my ass. Let's not forget broken Doze and some obnoxious wakelocks on 192 which are there propably to fix broken doze.
[Mate 8 General] Apad121:
What about B193?

I just got L29 4gb ram model of this phone. I have achieved 8.5 hours of sot before....

Maybe B193 has improved the power management?
[Mate 8 General] sharkonland:
B211 is pretty good for me, also i think its the latest official build as its android security patch november 2016.. Getting around 7-8hrs sot with it, mixed use gaming, browsing, instagram. Was getting around 6hrs with b320.

I will admit, standby is probably the worst part about the battery life, and thats on all roms I've tried. So maybe its the hardware, i.e. kirin chipset. It loses around 2-3 percent an hour, display off doing nothing. Meanwhile my iPhone 7 loses 2 percent in 12 hrs, but sot is about 4-5 hrs. So the mate is still much better overall as no one uses their phones by not using it, right.

Edit: Forgot to mention, On all the roms I've used i have noticed my main power consumption seems to be "Android System" at just over 70%, which is nuts.

If you go to phone manager, touch battery % remaining, consumption level you will see what is draining the battery. On my device the cpu time used by android system is around 10 hrs. And when i installed Cpu Spy to see if the device was going into deep sleep mode, it has been. So not sure whats the issue.

Guess there is only one option left. Keep using *cough*playing*cough* with my phone for further "testing".
[Mate 8 General] shadovraven:
I don't have this one yet but I highly doubt this. This is common for all devices, not just Mate 8. I remember when I had my Note Edge. It had excellent battery life on Kitkat, poor batter life on lollipop and garbage battery life on Marshmallow. That happens when producer release half assed updates.

Not really, on 152 Standby is excellent. That's because Doze works. Sadly Huawei failed to implement it right way, along with their module, to close apps when screen is off. The problem's that 152 has issues with notifications because of Android Doze. I can assure you, that you should never lose 2-3 % per hour, on B152 I lose 1% per 10 hours and that's how it should looks like. If it doesn't it's either:

- ****ty firmware version,

- Wakelock issues of some sort.

Bottom line's: If you want to use full potential of your phone, use it with oldest firmware. The newest one is just there, to convince you to buy Mate 9 i believe because it's so abnoxious.
[Mate 8 General] sharkonland:
I think we might be on to something about newest firmwares being a fraud essentially. I noticed with my Samsung Galaxy note 1. At release, which is when i bought it, battery and performance was ok, about 3 months in, both were fantastic and around the time note 2 came out, and device went from android 2.3 to latest version, battery life was down easily 30-40 percent while not being as fast. Same happened to my s3, s4 and note 3.

However, in their defence, they might not be able to allocate the same resources to updates as not much to gain apart from customers and media perception of manufacturer reliability. So that surely must play a role in it as well.

I ultimately still feel, they trick you with fancy new updates while likely under optimising the device to make it slow and fell like its time to upgrade. Thats why im hesitant to try 7.0 fw's until stable release is out and the numbers are positive.
[Mate 8 General] Oziguner:
Hi all mate 8 users ,

I'm going to talk about the exact solution of the battery drain problem.

You know that one of the most important features of this wonderful device is that it can be used for a long time without recharging it with 4000 mAh battery. The average screen time taken by users is 8-10 hours. You can finish this in 1 day as well in 3 days.

When I picked up the phone, the screen time rang between 4-5 hours, some users reported the same situation. I searched for foreign resources, read dozens of pages, and yes some users were able to take advantage of only half of that great screen!

The diagnosis of the disease was very obvious, the phone was in standby mode and sleep mode and consumed too much charge. Users have offered a lot of solutions, such as applications running at the back of the program or something did not benefit them all as a story.

I started testing the phone in a lot of ways, and I finally got the source of the disease. The problem is entirely due to VODAFONE operator lines. When the 3G is on, the phone is in standby mode and sleep mode consumes too much battery. (Consumes 10-12% of the charge in the morning from the night) (Consumption level android system seems to be working 50-60%)

Leave your mobile data only at Gsm 2G at night before sleeping, WiFi and everything you want is clear, your battery loss will be only 1-2%.

The other operators TURKCELL line users are experiencing 1-2% loss between morning and night at 3G open. So the problem is only for vodafone.

Could this be real in 2017? yes I think vodafone lines are not compatible with huawei and some brands of devices. ( for Turkey )

Maybe the problem is the same in your countries, my recommendation is to investigate this.
[Mate 8 General] robert_123:
Great discovery man, thank you.

I can confirm. I have dual sym Mate 8 with VIPNET (Vodafone) and TMOBILE cards.

I had VIPNET card set to be data card, my standby drain was 25-30% over night.

After your post I set TMOBILE card to be data card, now my standby drain is 3 %.

Someone in HUAWEI shoud investigate.
[Mate 8 General] Samavb:
Phone idle - battery drain - NXT-AL10

Hi,

What you wrote is totally true.

I have AT&T and ever since they shut down 2G services, 3G has been draining the battery in standby mode.

same 10-12% drain between night and morning. Nougat or Marshmallow - same problem persists. I tried both.

Android System not consuming 50-60% but it is definitely high.

Yes switching to 2G mode does help alot.

Unfortunately AT&T shut 2G here in US so I am still searching for an answer. :(

Hope someone has solution for AT&T problem. Everyone else just switch to 2G and you can resolve this issue. :o

Cheers!

[MENTION=1867148]Pfeffernuss[/MENTION] haha its not that bad actually. the impact in performance during everyday operation is almost unnoticeable. besides, huawei's powersave mode is actually kinda "leaky", so it still allows the cpu to reach higher clocks when necessary, only that it does so much more seldom :)

So the changing of governors still does not function properly at all ;)

No biggie though, battery life when using stock kernel/governor still is amazingly good, imho :good:
